IntelliJ 2017 is slow
Answered
It seems that everything got slower in IntelliJ 2017. Along with things like much worse OS file dialog (the original IntelliJ file dialog was much better), much less clear and less responsive search dialog it makes me feel Intellij 2017 is a step backward.
Regarding performance, the most annoying thing is that when I run a build from an external tool like Gradle and then focus on IntelliJ window, it reloads something, reindex something but there is really nothing to do because the affected directories are excluded. It becomes really unresponsive for that time. It didn't happen in IntelliJ 2016.

`-Dide.find.as.popup=false` in Help | Edit Custom VM Options will restore the original Find in Path dialog.
Add `-Dnative.mac.file.chooser.enabled=false` using Help | Edit Custom VM Options: https://intellij-support.jetbrains.com/hc/articles/206544869 to use non-native file chooser. This behavior is by design: https://youtrack.jetbrains.com/issue/IDEA-100279.
Please file an issue with the reproducible test case at https://youtrack.jetbrains.com/issues/IDEA regarding your reindex problem. Also provide the CPU snapshot: https://intellij-support.jetbrains.com/hc/articles/207241235.
Thank you, really appreciate!
Dead thread, but I have to add here that I also find the new "Find in Path" file dialog to be awfully slow. How in the world have they managed this?! If they don't fix stuff like this they will definitely start losing users.
If the new dialog is slow for you, please submit the proper report with the CPU snapshot as described above, we do not observe this problem, so it must be specific to your projects/environment.
